FRONT AXLE PARTSNLAX0005Check front axle and front suspension parts for excessive play,
cracks, wear or other damage.
+Shake each front wheel to check for excessive play.
+Make sure that cotter pin is inserted.
+Retighten all axle and suspension nuts and bolts to the speci-
fied torque.
Tightening torque:
Refer to SU-4, “FRONT SUSPENSION”.
SFA805B
FRONT WHEEL BEARINGNLAX0006+Check that wheel bearings operate smoothly.
+Check axial end play.
Axial end play:
0.05 mm (0.0020 in)
If out of specification or wheel bearing does not turn smoothly,
replace wheel bearing assembly.
Refer to “Wheel Hub and Knuckle”, “FRONT AXLE”, AX-5.

1. Remove brake caliper assembly.
2. Remove wheel bearing lock nut.
3. Remove brake rotor (models with disk brake) or brake drum
(models with drum brakes).
4. Remove wheel hub bearing from spindle.
CAUTION:
Do not disconnect brake hose from caliper.
+Suspend caliper assembly with wire so as not to stretch
brake hose.
+Be careful not to depress brake pedal, or piston will pop
out.
Make sure brake hose is not twisted.

5. Remove the sensor rotor using suitable puller, drift and bea
ring replacer.
